Objective To study and discuss intervention effects of prenatal eugenic screening in birth defects. Methods From January 2013 to December 2015, we did retrospective study on the clinical data of 69 183 cases of pregnant in which there were 69 262 fetal cases, made prenatal eugenic screening for all pregnant women. Prenatal screening results were analyzed, fetal abnormal cases were calculated. We took appropriate prenatal intervention measures, and followed up pregnant women who had no detection of fetal abnormal. We observed the pregnancy outcome, and calculated the defected childbirth cases and prenatal screening miss rates. Results 69 262 cases of fetus, a total of 7 470 cases of fetal abnormalities were detected. The fetal abnormality rate was 10.79%, of which 1 910 cases were in 2013, 2 569 cases in 2014, 2 991 cases in 2015. The detection rates respectively were 9.15%, 10.70%, 12.17%. 98 cases were determined as fetal birth defects by the final prenatal diagnosis examination, in which all adopted induction of labor to terminate pregnancy. 61 792 cases who were not detected anomalies were followed up in which 17 cases of fetus were found and had abortion during pregnancy, and 9 cases of fetal birth defects were delivered . The incidence of birth defects was 0.1 457 ‰, the prenatal screening miss rate was 0.1 456 ‰. Conclusion Pregnant women were made prenatal eugenic screening and according to the result of prenatal screening we took corresponding intervention, which is effective detect abnormal fetus. We may have timely termination of abnormal pregnancy,and reduce birth defects. It may promote human eugenics.

Objective To investigate the expression and clinical significance of Sonic hedgehog(Shh), Glioma-associated oncogene homolog -1(Gli-1) and Matrix metalloproteinase-2(MMP-2) in gastric cancer.Shh and Gli-1 are the molecules of Hedgehog(Hh) signaling pathway. MMP-2 is the member of matrix metalloproteinase family. Methods The expression of Shh,Gli-1 and MMP-2 proteins was examined by immunohistochemistry in the human gastric cancer tissues and the human gastric polyp and the normal gastric mucosa tissues of 40 cases. Results The positive expression rates of Shh,Gli-1 and MMP-2 in gastric cancer were 62.5%,67.5% and 72.5% respectively, which were significantly higher than those in the gastric polyp tissues (the positive expression rates were 27.5%,37.5% and 32.5% respectively) and normal gastric mucosa tissues (the positive expression rates were 22.5%,17.5% and 12.5% respectively),P<0.05.The expression of Shh,Gli-1 and MMP-2 was not correlated with the sex,age or histological type(P>0.05),but was correlated with depth of invasion,differentiation level and lymphonode metastasis in gastric cancer(P<0.05). The expression of Shh and Gli-1 was positive correlated with MMP-2. Conclusion Hedgehog(Hh)signaling pathway may have great effects on enhancing the invasive ability of gastric cancer by upregulating MMP-2 protein through some unknown mechanisms.The combined detection of the expression level of Shh,Gli-1 and MMP-2 in gastric cancer tissues might be used as an Objective references for assessing the prognosis of gastric cancer.

近年来的研究已经报道证实了白细胞介素-33(IL-33)及其受体ST2可以保护心衰病人因机械应力过度牵拉所导致的心肌细胞肥大、心肌纤维化的发生以及可溶性ST2受体可作为潜在的心脏机械超负荷生物标志物。而对IL-33与受体ST2在动脉粥样硬化过程中发挥的作用少有涉及。本文主要探讨的是IL-33和ST2对抑制Th1/Th2漂移从而影响到动脉粥样硬化的进展以及血浆中可溶性ST2受体蛋白升高的意义。
Recent study has reported that interleukin-33(IL-33) and its receptor ST2 could prevent cardiomyocyte hypertrophy and exaggerated interstitial fibrosis which is because of the over harmful biomechanical force in patients with heart failure and soluble ST2 receptors is the potential biomarker of cardiac biomechanical overload. But few studies mentioned the sort of IL-33/ST2 complex plays a role in atherosclerosis. The purpose of this article is to explore the IL-33 and ST2 could reduce a Th1/Th2 shift. Consequently, it may improve the development of atherosclerosis and significance of soluble ST2 receptor increased in plasma.
